Overtoun Bridge

Overtoun Bridge, on the approach to Overtoun House.

Overtoun Bridge is a category B-listed structure over the Overtoun Burn on the approach road from the west to Overtoun House, near Dumbarton in West Dunbartonshire, Scotland. It was completed in 1895, based on a design by the landscape architect H. E. Milner.

Since the 1950s, numerous reports of dogs either falling or jumping from the bridge have been reported. With the incidents often resulting in serious injury or death upon landing on the rocks some 50 ft (15 m) below, the bridge has been dubbed the "Dog Suicide Bridge". Various explanations for these deaths have been proposed, ranging from natural accidents to paranormal activity.

History and construction

Bridge with decorative bartizans.

In 1859, the Overtoun Farm was acquired by Scottish industrialist James White, who had just started in the business of chemical manufacturing. He built the Overtoun House three years later in 1862. When White died in 1884, his son, John Campbell White, inherited the house and its estate and started planning to extend the driveway of the house across a deep ravine in order to provide easier access. He hired landscape architect and civil engineer Henry Milner to design a bridge.

The bridge, which is constructed from rough-faced ashlar, was completed in June 1895. It comprises three arches that span a steep sided ravine. A large central arch spans the Overtoun Burn with two lower and smaller arches flanking both sides.

Unexplained phenomena

The bridge spans a deep ravine.

Pet dogs

During the 1950s, locals started referring to the bridge as the "Bridge of Death" or the "Dog Suicide Bridge", as it was reported that dogs were leaping from the bridge into the ravine below. The story gained more prominence during the late 2000s and early 2010s.

In 2004, Kenneth Meikle was walking with his family and Golden Retriever, when the dog suddenly bolted and jumped off the bridge. It survived, but was traumatized by the experience. Going into 2005, at least five other dogs also jumped over the course of six months. In 2014, Alice Trevorrow, who was walking with her Springer Spaniel named Cassie, reported a strange experience on Overtoun Bridge. "I had parked up and as she is so obedient I didn't put her lead on... Me and my son walked toward Cassie, who was staring at something above the bridge... she definitely saw something that made her jump. There is something sinister going on. It was so out-of-character for her."

In 2019 Bob and Melissa Hill, the owners of Overtoun House, said that in 17 years of residing at the House, they had witnessed a number of dogs become agitated and fall from the bridge. Bob Hill stated that the scent of mink, pine martens, and other animals agitated the dogs, resulting in their jump onto the bridge wall: "The dogs catch the scent of mink, pine martens or some other mammal and then they will jump up on the wall of the bridge. And because it’s tapered, they will just topple over." Hill, who was originally a pastor from Texas, also stated he believed the grounds around the House possessed some sort of spiritual quality.

A number of theories have been proposed as to what is affecting the behaviour of dogs on the bridge. In 2014, canine psychologist David Sands proposed that the surrounding foliage – giving the in-reality extremely steep drop off the side of the bridge the appearance of even ground – combined with the residual odor from male mink urine in the area could be culprit for luring dogs to jump off the bridge. However, John Joyce, a local hunter and resident of 50 years, rejected this theory stating that there were "no mink [in the area]". In a separate investigation by the Royal Society for the Protection of Birds, it was found that the side of the bridge reportedly favoured by leaping dogs did contain evidence of "nests of mice, squirrels, and minks". In a separate experiment, seven out of ten dogs exposed to canisters filled with the scent of mouse, squirrel and mink, "all went straight for the mink scent, many of them quite dramatically."

The Scottish Society for the Prevention of Cruelty to Animals has also investigated the bridge and surrounding area but their findings proved inconclusive.

Some local people think that there is supernatural activity around the bridge and Overtoun House, which could be luring dogs to their deaths because animals are sensitive to the paranormal.

Human tragedy

In October 1994, while suffering from an episode of paranoid schizophrenia, Kevin Moy threw his two-week-old son Eoghan to his death from the bridge because he believed that his son was an incarnation of the Devil due to a birthmark. He said that he chose the location due to its association with dark spirits going back to the druidic days. Following the killing, Moy attempted to commit suicide but he was caught and placed in a mental health hospital.

In film and television

In October 2022, Heel Films used Overtoun House, the bridge and the alleged paranormal activities as a basis for their 2023 short film "The Bridge" written and directed by Scott McMillan; the short film stars Christopher Wallace and Susan Sims.
